• Can URIs have non-ASCII characters?

  - by Cheeso

  I tried to find this in the relevant RFC, IETF RFC 3986, but couldn't figure it. Do URIs for HTTP allow Unicode, or non-ASCII of any kind? Can you please cite the section and the RFC that supports your answer. NB: For those who might think this is not programming related - it is. It's related to an ISAPI filter I'm building.

  - by Albert Widjaja

  Hi, I'm using MS TMG 2010 Standard as my single firewall to publish my Exchange Server and IIS website to the internet, however it is just one VM in the DMZ network with just one network card (vNIC), what sort of redundancy method that is suitable for making this firewall VM redundant / automatically failover in my DR site ? Because it is very important in the event of disaster recovery all important email through various mobile device will still need to operate and it is impossible if this TMG 2010 VM is offline. is it by using: 1. Multicast NLB 2. Any other clustering 3. VMware HA / FT (one VM in production, the other VM in DR site with different subnet ?) Any suggestion and idea willl be appreciated. Thanks

• Do you need a good background in OOP before moving to frameworks?

  Frameworks being all OOP, would it not be wise to go into frameworks without having a solid background in OOP? I can write basic classes but nothing too fancy or abstract. How much should I know of OOP before moving to frameworks? Right now I am PHP Object-Oriented Programming to learn OOP.

• Improving as a coder with respect to design.

  - by dmarakaki

  As a soon-to-be computer science graduate, I have to come realization that I have a long way to go when it comes to the overall design of an application. After spending many semesters of programming from the hip I have come to appreciate the mulling over the needs of an application before diving head first into the coding portion. My question is to the intermediate and expert programmers, how can I improve in the area of the design phase of development?

• How can I connect any USB device to my computer wirelessly?

  - by daviesgeek

  I am trying to connect the Canon 550D wirelessly to my computer so that I can control it from at a distance. It can connect normally via a USB cable, so I was wondering if there was a way to plug a dongle into the computer, and a dongle into the camera so the two can connect. I'm basically looking for a really long USB cord that will work over long distances (200+ feet). Another important factor is that I really would prefer not having use a power cord, rather just plugging in a dongle, as it will make the setup more mobile. Does anything like this exist? (I know that Cables Unlimited had something like what I wanted, but they went out of business last year)

• SVG -- Replacement for Flash application

  - by Vadi

  We are currently looking at developing flash based applications (using Flex) in a web application. We are now leaning towards to use SVG rapheljs for developing this components. The questions are: Is still SVG platform is widely adopted by browsers (without any plug-ins) are at least down the line of 8-10 months, any adoption is expected by browsers? Cross-browser support is god for us. Is SVG can replace for a small time animation based programming instead of Flash Any comments will be greatly appreciated...

• How to log the actual output in apache?

  - by Oscar Rodriguez

  I am doing LAMP development for a mobile platform. However, the client browser does not allow me to view the source code of visited pages. I consider the source code to be of huge importance for debugging, so I would like to configure my web server so every time a user makes a request, in addition to sending the client a response, that response (the actual contents of the returned page) is also stored in a file with a filename I can cross-relate with access_log (maybe ip-timestamp-filename? or maybe a unique ID in an additional column in access_log?). I've searched quite a bit, but haven't even gotten close to finding what I'm looking for. Has anybody been able to do this?

• Tips on a tool to measure code quality?

  - by Cristi Diaconescu

  I'm looking for a tool that can provide code quality metrics. For instance it could report very long functions (spaghetti code) very complex classes (which could contain do-it-all code) ... While we're on the (subjective:-) subject of code quality, what other code metrics would you suggest? I'm targetting C#/.NET code, but I'm sure this could extend to most programming languages.

• Is Flash/Actionscript any safer than Javascript for persistent online game?

  - by Sean Madigan

  I'm finding lately how unsecure Javascript is when programming a game (I'm trying to do a turn based RPG and currently the battle calculations are done through Javascript which any player can cheat with of course giving themselves as much XP as they want), so I'm wondering if I were to move my battle screen to flash if this would be any more secure, or is there just as easy of a way to cheat this?

• Remote control a computer using another computer

  - by Dean

  I've got a main desktop computer at home, I'd like watch movies using it but able to control it afar. For example, I would like to lay on my bed and control the desktop using my own laptop via wireless. I've been looking for solutions to my question. I tried to use remote desktop, I can pause the movie but I then have to go to the pc to log in the OS again. I also tried to bind my desktop to my mobile phone over bluetooth, this works as I can control the mouse etc. but I found I can barely see the mouse pointer when at long distance. I still wish I can use my laptop as a remote control, is this possible?
